Yellow-throated bulbul (YTB), Pycnonotus xantholaemus is an endemic and threatened bird of the Deccan Peninsula which is found in discontinuous populations. We used MaxEnt algorithm to generate environmental niche models for further surveys. We compared the models for current and future scenarios to assess change in the extent of suitable habitat in response to climate change. We used 102 verified presence locations and six environmental variables: four climatic, one topographical and one vegetation layer to generate the final model. Topographic rug-gedness index and precipitation of wettest month were the major predictors of suitable habitat. The predicted distribution amounting to 7% of the Deccan Peninsula was highly fragmented. Only 13.5% of the predicted habitat fell within the Protected Areas. Models pre-dicted 6.5%–42% loss of habitat in different climate change scenarios, with a marginal gain in the western slopes of southern Western Ghats. Microclimatic fea-tures of the habitat may help determine the geographic distribution of YTB. This could serve as a non-traditional flagship species to highlight conservation of rocky outcrops in the Deccan Peninsula.Keywords

Hangul Cervus hanglu is the only red deer species in India distributed in the Kashmir Himalaya. A population of only 200-odd is currently surviving in the wild due to a variety of threats since prehistoric times. Given the critical nature of this population, use of multifaceted approaches and technologies along with addressing the prerequisites to a successful conservation breeding programme, remains crucial to enhance the reproductive value of such endangered species. We expect that the information on genetic diversity, reproductive biology and dietary niche of wild population, generated through the ongoing work would speed up the species conservation efforts.Keywords
